Front border flower suggestions?
I'm looking to stop using so many annuals and instead using more perennials for the front and to a lesser extent the middle of my borders. But for that I need things that will flower for long periods here in my Zone 5 (Toronto) and in full sun. Preferably non-invasive.
I have a variety of different beds and companion plants and colors so almost anything will likely work in a spot!
RIght now for border edges I am using:
Dianthus (Cheddar Pinks)
Scabiosa Pink Mist (Dwarf Pincushion Flower)
Nepata Walker's Low
Hardy Geraniums and Cranesbills
Is there anything similar to Alyssum except as a long-flowering perennial? That is the effect I am going for with the Iberis and Rock Cress edging but those do not flower through the summer. I was looking at Baby's Breath but I read that it is very invasive.
